Head-body 50-6 62-4 mam, tall 36-7-57 mm, car 11.5-16 mm, hindfoot 10-5-12-1 mm, forearm 37-42 mm; weight 13-22 g. The Narrowwinged Pipistrelle is considerably larger than all other species of or and is more Nyctaluslike. Muzzle is broad and thick, and wings are narrow. Pelage is short. Dorsum is dark reddish brown to dark chocolatebrown; venter is slightly paler and grayer. It might be sexually dimorphic, with females being reddish brown and smaller and males more brownish or grayish brown and larger. Ears are of moderate size and somewhat rounded (butstill subtriangular), with broadly rounded tips; tragus is broad, hatchetshaped, and strongly angled forward. Uropatagium extends from calcar to nearly tip oftail; only extreme tip is free. Fifth metacarpal is much shorter than fourth metacarpal, which gives its characteristic narrow wings that differentiate it from other species of Pipistrellus . Baculum is ¢.3-5 mm long (relatively short compared with Asiatic congeners) and more massive than in other Pipistrellus but gradually narrows from base to end; end is wider and bifurcated; tip points downward; and base has deep and narrow notch. Skull is large and broad, with short thick rostrum; braincase is rounded; there is no frontal depression; sagittal crestis well developed; supraorbital tubercles are well developed; zygomatic arches are moderately developed; post orbital processis slight; C! is large, with slight posterior cusp; I* is bicuspid, and I” is unicuspid or with very small secondary cusp; P? is large and within tooth row; and lower molars are nyctalodont. Chromosomal complement has 2n = 32 and FN = 50 ( Malaysia ).	Lowland foothills, montane regions, plantations, and urban areas at elevations of 100-1200 m. In Lampung Province , southern Sumatra , the Narrow-winged Pipistrelle was recorded in a coffee plantation and coffee-rubber mixed plantation.	The Narrow-winged Pipistrelle is insectivorous. It forages over streams and open fields and around streetlights.	No information.	The Narrow-winged Pipistrelle is nocturnal and seems to be a highflying bat. It roosts in hollow trees in plantations and gardens and roofs of houses. Call shape is FM/QCEF, and search call has durations of 2—4 milliseconds and sweeps of 30-60 kHz. In the Krau Wildlife Reserve, central Peninsular Malaysia , two different feeding calls (low and high frequencies, respectively) were recorded with starting frequencies of 42.8 kHz and 56 kHz, terminal frequencies of 28 kHz and 32-9 kHz, peak frequencies of 31 kHz and 37 kHz, and durations of 13-8 milliseconds and 9-7 milliseconds.	The Narrow-winged Pipistrelle is gregarious and will roost with the Lesser Asiatic Yellow Bat ( Scotophilus kuhliz ).	Classified as Least Concern on The IUCN Red List. The Narrow-winged Pipistrelle is rarely caught, likely because it flies high and is hard to catch. It does not seem to face any major threats. In Singapore , it was not collected from 1986 to 2010 and was considered extinct from the island during that time.	Bumrungsri et al.

In Thailand and Malaysia the species has been mist netted whilst feeding over streams and open fields (Payne et al . 1985) and Medway (1983) reported it in lowland foothills. It is found from about 100 m asl (S. Bumrungsri pers. comm. 2006), elsewhere its upper elevational range has been recorded as 1,200 m asl. This species is gregarious and roosts in hollow trees and plantations, roofs of rural areas, and occasionally is found with Scotophilus kuhlii .	There are no major threats to this species.	This bat is rarely caught as it is likely to be a high flying species it is probably under represented by surveys and have not been caught for the past 18 years in the Philippines (Tanalgo and Hughes 2018). The global population is not unlikely to be in significant decline.	Unknown	This species is found on Sumatra and Borneo (Suyanto et al.  1998, Khan 2008, Huang et al.  2014), through to the Philippines where it is known from a single specimen from Mindanao (Zamboanga del Sur Province) (Heaney et al.  1998, Tanalgo and Hughes 2018). It also occurs in Peninsular Malaysia (Khan 2008; Jayaraj et al.  2013a,b, 2016; Lim et al.  2017) Singapore and southernmost Thailand (Bumrungsri et al.  2006, Soisook 2011).		Terrestrial	The species occurs in a number of protected areas throughout its range but is lacking of data in the Philippines where there is need to reexamine its occurrence and distribution.
